' sections, and a series of horizontal equally spaced walls l9 which are penetrated by and may be soldered to the rods. The rods extend somewhat below the lowest wall and so afford feet which rest on the bottom of the chamber. walls are all formed with relatively small holes l9a (Fig. 6), such being the same in number and similarly positioned in all the walls, or so that a hole in any one wall is vertically alined with corresponding holes in the other walls. Each of the alined holes in the several walls receives a foraminous tube 20. To form each tube I take a rectangular strip of fine-mesh wire netting 20a (much finer than is shown in Fig. 7) and roll it so that its long edges lap each other as shown in Fig. 6 and then enter it into the alined holes, its consequent effort to expand securing it in position. At the bottom ends the tubes may be flush with the lowest wall, but at the top they upstand therefrom somewhat. The construction is such that the unit, or in this example each section thereof, may be removed intact by lifting it from the chamber.

- below the braces 8 and i5.

The top of the chamber i6 is provided at opposite sides with interior ledges 2| and on these rests a grid including spaced louvers or vanes 22 which are V-shaped in cross-section and parallel, their convex sides all facing in the same direction.

The topmost wall l9 affords adistributing surface for the liquid (as water.) with which the fluid (as air) impelled by the blowers is to be saturated. Arranged over this surface and in a plane cutting it centrally is arranged the horizontal discharge end portion of a pipe 23 which extends upwardly between the housing 5 and said chamber from a pump 24 arranged on the bottom of the housing, to wit, in a tank 25 for the liquid, such tank being arranged in the space of the housing The rotor of this pump is driven by a flexible shaft 28 connected with the shaft of the motor and blowers so as to rotate therewith. By apertures 23a the pipe 23 is adapted to spray liquid over the surface of the topmost wall l9. The lowermost wall it may have drain-pipes 21 which discharge into the tank. a

The liquid may be supplied to the tank through a pipe 28 subject to the control of a float valve 29. To secure the shell 5 and chamber 18 against displacement on their supporting braces there may be two rods 30 which flank the shell on both sides and are attached each at one end to the chamber and at their-other ends extend through the wall of the housing between which and the chamber the shell is arranged and are threaded and receive clamping nuts 3!.

Operafiom-When the system including the motor, blowers and pump is driven there is a flow of atmospheric air through shell 9 into chamber it, up through the foraminous tubes 20 and thence through the nozzle to; the warp (the baifies or louvers 22 dispersing the air at the outlet to and -tially its entire surface.

through the holes lsaworks down each tube as The several topmost wall l9 and to the blasts of air upwardly passing therethrough thewater tends-to collect on the top wall, being distributed over substan- The water falling a film and may incidentally collect somewhat on each of the several walls. The air passing up through the chamber 15 is not of course confined to the spacesof the tubes, but by some expansion and contraction'penetrates the foraminous wall of each tube. In any event, as an incident of the film-condition of the water existing on the tubes taken with the rapid motion of the air and its effort to pass through the fine interstices of the tubes and hence through the water-film thereon the water becomes divided into molecular state and in that state charges the air. There is thus delivered a fluid which is quite humid or comprising a gas (air) having a liquid (water) existing only in molecular suspension. Further, the fluid thus delivered is quite cold as distinct from being merely cooler than the air in its original state, this being an incident of the appreciable evaporation which of course takes place with respect to the liquid in its stated minutely divided form.

The fluid delivered by the nozzle of course conveys its moisture to and deposits it on the warp and by absorption of such moisture the threads of the warp, otherwise left more or less deprived of moisture by the heat of the drums, retain that soft and supple state which characterized the threads before undergoing the sizing treatment; the absorption being enhanced because of the still heated condition of the sized warp. Since this fluid is cold the Warp becomes wound into the wound mass not only without possibility of the size acting to cement the threads together but without conveying to such mass heat which, accumulating in the mass, would act therein to dry out the threads.

In addition to the method involved in the treatment of a warp according to this invention I claim also certain novel features of the apparatus shown in detail in Figs. 2 to 5. Of course my invention may be applied to other fibrous textile sheets than sheets of warp.

It is not material whether the blast delivered thesheet and means to heat the sized portion of v the sheet, gas impelling means, means to humidify the gas, and means to deliver the humidified gas to the sizedsheet posterior to the point of heating. the same including a nozzle having a mouth elongated across the sheet and a baffle within the mouth also extending across the sheet.
